Parser Error In Portlet Startup

Question

We have a portlet application that uses Crystal Reports. It uses the spring framework and runs fine in our development environment (Pluto) but when trying to deploy on the production environment (WebSphere) we get an xml parsing error during the startup. Removing the Crystal Reports jars solves the problem but of course the reports portion of the application won't work. So is there a different set of jars for portal and specifically WebSphere? Or is there xml related functionality in the CR jars  and would eliminating them from the lib solve the problem since there may be framework jars that provide the same functionality in the production environment?
Here's a snippet of the error:
Unexpected exception parsing XML document from ServletContext resource [/WEB-INF/sys-cfg/applicationContext.xml]; nested exception is java.lang.VerifyError: javax/xml/parsers/DocumentBuilder.setEntityResolver(Lorg/xml/sax/EntityResolver;)

Answer 1

The only officially tested and fully supported product for Crystal Reports on Portal Servers/Portlets are the JSR-168 Portal Integration Kits supplied with BusinessObjects Enterprise or Crystal Reports Servers. 
There's currently not a fully tested Portal solution for Crystal Reports Java Reporting Component.
There's no different sets of jars for different Web Application Servers with any Business Objects products.
Are you able to isolate which XML file contains the problematic schema?  I'm assuming the error message you have does not show this info.
Other than that, a possible difference is that different XML parsers are being used between your dev and prod web app servers.   I've known issues where the XML parser supplied with Crystal was incompatible with the shared default parser supplied with Web App Servers.
